You are probably right, the problem is in the runtime libs. Can you
check and compare the versions for MS C runtime dlls?
Another idea is something like antivirus (or virus) that modifies
the executable code while loading it in memory.

Hi Aleksey,
I have had this xmlsec application (now at 1.2.18) working for
several years without incident on Windows XP, Vista, and even Windows 7.
However on selected machines that I run the application on, I get an I/O
error related to buffer flushing and C14N canonicalization. This only
happens on certain Windows XP machines and I think it is related to some
run-time executable (.dll or exe) outside my environment.
Here is the summary trace of what comes out on the console .... note
where there error occurs between xmlSecDSigCtxInitialize and
xmlSecDSigCtxSign
input buffer follows .... write to stdout from my application

Any ideas which .dll .exe may be missing, wrong version, etc ....
Many thanks . . .
